[Preliminary diagnostic measures for performing hyperbaric oxygen therapy in a diving accident].

A diving accident may occur during working and leisure time, scientific or archaeological investigations, even during police duty. It is therefore necessary to carry out several preventive measures. The therapeutic treatment based on oxyhyperbaric recompression, is a medical therapy that needs a precise diagnosis and an evaluation of contingent associated pathologies. The following elements have to be checked on the diving place: the anamnestic data, the diving outline and the symptomatology, together with the usual clinical tests. The clinical survey will be completed in hospital, including electrocardiogram, thorax x-ray and laboratory tests. CT-scan, NMR and Evoked Potentials may be considered complementary actions to be taken, according to perceived needs.
